SPECIFICATION forming part of Letters Patent No. 600,804, dated March 15, 1898.

Application filed March 2 9, 1 8 9 7.

To aZZ whom it may concern.-

Be it known that I, EDWARD SOHAEFER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to chemical fire-extinguishers; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is a top plan view. Fig. 2 is a side elevation, partly in section, taken approximately on the line 2 2 of Fig. 1, parts being broken away to economize space. Fig. 3 is a bottom plan View of the rack which holds the acid-bottle. Fig. 4 is a vertical sectional View through the cap of the fire-extinguisher and a side elevation of the rack and acidbottle, showing a modification of the construction shown in Fig. 2. Fig. 5 is a side elevation of the fire-extinguisher, showing means of holding the acid-bottle closed when the fire-extinguisher is off the hook and resting upon its base upon the floor, parts being broken away to economize space. Fig. 6 is a front view of the cap of the extinguisher, and Fig. 7 is a side view of the parts shown in Fig. 6. The constructions shown in Figs. 6 and 7 are modifications of the construction shown in Fig. 5.

Referring by numerals to the drawings, 10 is the main tank of the fire-extinguisher; 11, the chemicals which are to be mixed with the sulfuric acid; 12, the acid-bottle containing the sulfuric acid, which bottle is suspended of my invention.

in the tank in accordance with the principles The upper end of the main tank 10 is closed by the cap 13, which cap is removably screw-seated in position. An interiorly screw threaded nipple 14 projects from one side of the upper part of the tank 10, and a pipe 15 has one of its ends screwseated in said nipple and communicates with the interior of the tank:

In the center of the cap 13 is a circular opening in which the bolt 16 is slidingly mounted. A packing-ring 17 is placed upon the bolt 16 below the cap 13, and the saucershaped cap 18 is attached to the lower end of the bolt 16 and below the packing-ring 17 and Serial No. 629,765. (No model.)

in an inverted position. The soft packing 19 is fixed in position in the cap 18.

Extending upwardly from the upper surface of the cap 13 and near the inner edge of said cap is an ear 20. A lever 21 has a slot 22 approximately in its center, in which the car is inserted, and the bolt 23 passes horizontally through the lever 21 and through the car 20, as required to form a pivotal support for said lever. The inner end of the lever 21 is horizontally and vertically bifurcated. The upper end of the sliding bolt 16 is inserted in the vertical slot, and the bolt 24 is inserted in the horizontal slot and through the upper end of the sliding bolt 16, as requiredto form a sliding connection between the end of the lever 21 and the sliding bolt 16.

A loop 25 is attached to or formed integral with the opposite end of the lever 21 from the bolt 16, said loop being designed to be used as a handle for operating the machine and as a means of suspending the machine from the hook 26, which hook is inserted in the wall.

A circular recess is formed in the lower side of the lever 21, between the bolt 23 and the bolt 24, and a corresponding recess is formed in the upper face of the cap 13 in alinement with the first-mentioned recess, and an expansive coil-spring 27 is placed with its ends in said recesses, the tension of said spring operating to elevate the sliding bolt 16.

The acid-bottle 12 is mounted in the rack, consisting of the lower ring 28, the arms 29 and 30, projecting upwardly from said ring 28, the ring 31, connecting the upper ends of the arms 29 and 30 and mounted in position parallel with the ring 28, the arms 32 and 33, projecting upwardly from the ring 31 in alinement with the arms 29 and 30, respectively, and the door 34, operating to close the lower end of the ring 28. The ear 35 projects horizontally from the lower edge of the ring 28, and the bolt or rivet 36 is inserted through said ear 35 and through the car 37, formed upon the inner edge of the door 34, thus forming a pivotal connection between the door 34 and the ring 28.

A lug 38 projects downwardly from the edge of the ring 28 at the side opposite the car 35, and said lug is horizontally slotted from one of its sides. A lug 39 projects out wardly from the edge of the door 34 opposite the car 37, and when the door is closed the lug 39 engages in the slot in the lug 38. The lugs 40 project downwardly from the lower face of the door 34 to a point upon a level with the lower edge of the lug 38, and the lugs 38 and 40 form feet upon which the rack may rest when it is removed from the tank.

In the form of the device shown in Fig. 2 the upper ends of the arms 32 and 33 are rigidly attached to the cap 13.

In the modification shown in Fig. 4 an annular flange 41 projects downwardly from the cap 13 in position concentric with the bolt 1 6, said flange being interiorly screw-th readed, and a ring 42 is formed integral with the upper ends of the arms 32 and 33 and is exteriorly screw-threaded and screw-seated in said flange 41, thus forming a removable and adj ustable connection between the acid-bottle rack and the cap 13. The bottle 12 is inserted in the rack by opening the door 34 and passing said bottle upwardly through the ring 28 and then closing the door. The packing 19 engages the mouth of the bottle and closes the bottle when the handle 25 is elevated, and thehandle 25 maybe elevated in various ways.

In Fig. 2 the device is shown as hanging upon the wall, wit-h the handle 25 engaging the hook 26, which is inserted in the wall.

In Fig. 5 the ear 43 projects from the lower part of the tank in a horizontal position and is vertically perforated. The rod 44 is attached to the handle 25, with its lower end operating through the ear 43, and the rod 44 is of such a length that when the sliding bolt 16 is elevated by the expansion of the coilspring 27 the lower end of the rod 44 will project downwardly below the lower end of the tank 10, as indicated in dotted lines. When the tank is set down upon the floor, the lower end of the rod 44 will engage the floor and said rod will slide upwardly through the ear 43, thus elevating the handle 25 and depressing the packing 19 into engagement with the mouth of the bottle.

In the modification shown in Figs. 6 and 7 the ears 45 and 46 project upwardly from the cap 13 in alinement with the sliding bolt 16 and in aline transversely of the lever 21, and the bail 47 has its ends operating in the ears 45 and 46, and the eccentric 48 is pivotally mounted upon the central portion of the bail 47 and in position to engage theupper face of the lever 21 or the upper end of the sliding bolt 16. The handle 49 is attached to the eccentric 48 for operating the same, and the parts are so adjusted that when the handle 49 is depressed the sliding bolt 16 is depressed and the packing 19 is held in contact with the mouth of the bottle. When the handle 49 is elevated, the bail 47 will fall down upon the cap 13 and the lever 21 is free to operate by the expansion of the spring 27. The handles 50 project from opposite sides of the cap 13 for operating the same.

The chemicals or liquid within the main tank are expelled through the pipe 15 by means of the gas generated by the inversion of the tank 10 and the consequent commingling of the contents of the bottle 12 with the contents of the tank 10.

When the construction shown in Figs. 6 and 7 is used in connection with the construction shown in the other figures, the eccentric 48 serves as a means of locking the device and holding it inoperative for shipping purposes or for any purpose where it is desired to handle the fire-extinguisher without having the acids mix.
